LM2937ES-10 # 500 mA Low Dropout Regulator National Semiconductor
The LM2937 is a positive voltage regulator capable of supplying up to 500 mA of load current.
The use of a PNP power transistor provides a low dropout voltage characteristic.
With a load current of 500 ma the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5V
(1V ensured maximum over the full operating temperature range).
Special circuitry has been ncorporated to minimize the quiescent current to typically only 10 mA with a full 500 mA load current
when the input to output voltage differential is greater than 3V
The LM2937 requires an output bypass capacitor for stability.
As with most low dropout regulators, theESR of this capacitor remains a critical designparameter,
but the LM2937 includes special compensation circuiti that relaxes ESR requirements
The LM2937 is stable for all ESR below 30.
This allows the use of low ESr chip capacitors Ideally suited for automotive applications,
the LM2937 will protect itself and any load circuitry from reverse battery connections,
two-battery jumps and up to +60v/-50V load dump transients.
Familiar regulator features such as short circuit and thermal shutdown protection are also built in.
